gRPC PHP and GO data growth performance test and analysis

Preface

Hello, everyone. I’m CrazyCodes. I recently investigated how PHP requests go through gRPC and PHP requests through HTTP. According to the increasing amount of data, the average response time will be much different.

Declaration of conformity

The test reports are all tested by the development machine without any configuration changes.

Native configuration

• 3 GHz six-core Intel Core i5
• 16 GB 2400 MHz DDR4
• MacOs

Go start HTTP

http.ListenAndServe

PHP start HTTP

php -S 127.0.0.1:8088

test data description
As the server, Go is the test data iterated directly through for, without any other redundant operations

// 伪代码
for i := 0; i < 2,20,200,2000,5000; i++ {

}

According to the test results, it is not difficult to see that when building microservices, it is the most undesirable situation for PHP to request via gRPC. In terms of response time, PHP invoking via Http is slightly better than PHP via gRPC in terms of response time. Some, but with the continuous growth of data and concurrency, this gap will continue to grow. Therefore, when deciding to use PHP as the client, it is best to use the traditional HTTP method to call.

You must think that PHP has been crushed in doing microservices, but this is actually not a fault of PHP itself. We all know that PHP is an interpreted language, and Go is a compiled language. Go is pre-compiled and can be directly generated. Execute the file, and PHP is dynamically compiled.

So why is it so slow to call through gRPC in PHP? This depends on the package we use officially provided by Google. The package encapsulates the data in the class , and the class is not as small and exquisite as the structure of Go. When the data continues to grow, the class will expand exponentially, and we When I see that PHP is called through HTTP, although the content body is several times that of gRPC calls, the time is reduced. The reason for this is also very simple. is called through HTTP, and the communication must be carried out first, and the HTTP header is encapsulated, the content body Wait, this has caused the request body to be very large, but because it is a direct request for a result, and the class is not passed, the time is shorter than the gRPC call, which is one of the reasons why PHP uses gRPC slowly.

The second is what we call the characteristics of PHP itself, to the user after dynamic compilation. This process also takes time, but Go does not need this time, so this is also a key factor affecting response time.

Thank you for seeing here, I hope I can help you.
